Naruto may become more self - reliant. Since he's been neglected, he has to depend on himself more. In the DxD world, he learns new skills quickly as he doesn't have the support he once hoped for. This makes him a stronger and more independent character.
One interesting plotline could be where Naruto is neglected by his friends in the Hidden Leaf Village and then somehow ends up in the DxD world. There, he has to find his place while dealing with the neglect he's faced in the past. Maybe he forms new bonds with the characters in DxD who understand his pain.
It could also be due to personal relationships. Perhaps some of his closest friends get caught up in their own lives. Like Sasuke might be on a long - term mission and not be there for Naruto, and Sakura might be too busy with her medical studies. So Naruto, who is used to having a support system, suddenly feels alone and neglected.
I'm not entirely sure specifically what that particular 'naruto neglect crippled fanfiction' is about. It could be a fan - created story within the Naruto universe that focuses on themes of neglect and perhaps a character who is crippled. However, without reading it, it's hard to say for certain.
In Naruto fanfiction, family neglect can be shown in various ways. For example, Naruto's own upbringing was filled with neglect as he was shunned by the villagers. Fanfictions might expand on this by having his family, if they were alive, also be cold or distant. It could be that his parents, if alive, were too caught up in their shinobi duties to give him proper attention.
One reason for this in fanfiction could be to give Naruto a different kind of arc. Instead of the somewhat positive neglect in the original (where it was more about being alone but still having some hope), here it's a full - blown abandonment. And his near - death experience can be used to show how fragile he really is, despite his strong - willed nature in the main series.
In fanfiction, the 'Naruto x Yagura neglect' could imply a relationship where Naruto is somehow involved with Yagura, but there is neglect present. This might be explored in terms of their character interactions. For example, if Naruto fails to understand Yagura's past traumas which leads to a form of neglect in their relationship. It could also be a situation where the storyteller is trying to show the consequences of such neglect on both characters' development and how they deal with the emotional fallout.
One interesting 'Naruto Neglect Fanfiction' could be where Naruto is neglected by the village elders, but he finds his own path to power. Maybe he meets a hermit in the forest who trains him in unique jutsus.

People write 'Naruto Neglect Fanfiction' because it offers a different take on the original story. It allows them to explore how Naruto would develop if he faced neglect.
For Naruto, the consequence of family neglect in fanfiction could be a deep - seated loneliness. He might have trust issues, always doubting if people really care about him or just using him.
